86. #### case class Constant extends internal.SymbolTable.ConstantApi with Product with Serializable

    This "virtual" case class represents the reflection interface for literal expressions which can not be further broken down or evaluated, such as "true", "0", "classOf[List]".

    This "virtual" case class represents the reflection interface for literal expressions which can not be further broken down or evaluated, such as "true", "0", "classOf[List]". Such values become parts of the Scala abstract syntax tree representing the program. The constants correspond to section 6.24 "Constant Expressions" of the Scala language specification.

    Such constants are used to represent literals in abstract syntax trees (the scala.reflect.api.Trees#Literal node) and literal arguments for Java class file annotations (the scala.reflect.api.Annotations#LiteralArgument class).

    Constants can be matched against and can be constructed directly, as if they were case classes:

        assert(Constant(true).value == true)
        Constant(true) match {
          case Constant(s: String) =>  println("A string: " + s)
          case Constant(b: Boolean) => println("A boolean value: " + b)
          case Constant(x) =>          println("Something else: " + x)
        }

    `Constant` instances can wrap certain kinds of these expressions:

    1. Literals of primitive value classes (`Byte`, `Short`, `Int`, `Long`, `Float`, `Double`, `Char`, `Boolean` and `Unit`) - represented directly as the corresponding type
    2. String literals - represented as instances of the `String`.
    3. References to classes, typically constructed with scala.Predef#classOf - represented as types.
    4. References to enumeration values - represented as symbols.

    Class references are represented as instances of scala.reflect.api.Types#Type (because when the Scala compiler processes a class reference, the underlying runtime class might not yet have been compiled). To convert such a reference to a runtime class, one should use the `runtimeClass` method of a mirror such as `RuntimeMirror` (the simplest way to get such a mirror is using `scala.reflect.runtime.currentMirror`).

    Enumeration value references are represented as instances of scala.reflect.api.Symbols#Symbol, which on JVM point to methods that return underlying enum values. To inspect an underlying enumeration or to get runtime value of a reference to an enum, one should use a scala.reflect.api.Mirrors#RuntimeMirror (the simplest way to get such a mirror is again scala.reflect.runtime.package#currentMirror).

    Usage example:

        enum JavaSimpleEnumeration { FOO, BAR }

        import java.lang.annotation.*;
        @Retention(RetentionPolicy.RUNTIME)
        @Target({ElementType.TYPE})
        public @interface JavaSimpleAnnotation {
          Class<?> classRef();
          JavaSimpleEnumeration enumRef();
        }

        @JavaSimpleAnnotation(
          classRef = JavaAnnottee.class,
          enumRef = JavaSimpleEnumeration.BAR
        )
        public class JavaAnnottee {}

        import scala.reflect.runtime.universe._
        import scala.reflect.runtime.{currentMirror => cm}

        object Test extends App {
          val jann = typeOf[JavaAnnottee].typeSymbol.annotations(0).javaArgs
          def jarg(name: String) = jann(newTermName(name)) match {
            // Constant is always wrapped into a Literal or LiteralArgument tree node
            case LiteralArgument(ct: Constant) => value
            case _ => sys.error("Not a constant")
          }

          val classRef = jarg("classRef").value.asInstanceOf[Type]
                                                 // ideally one should match instead of casting
          println(showRaw(classRef))             // TypeRef(ThisType(), JavaAnnottee, List())
          println(cm.runtimeClass(classRef))     // class JavaAnnottee

          val enumRef = jarg("enumRef").value.asInstanceOf[Symbol]
                                                 // ideally one should match instead of casting
          println(enumRef)                       // value BAR

          val siblings = enumRef.owner.typeSignature.declarations
          val enumValues = siblings.filter(sym => sym.isVal && sym.isPublic)
          println(enumValues)                    // Scope{
                                                 //   final val FOO: JavaSimpleEnumeration;
                                                 //   final val BAR: JavaSimpleEnumeration
                                                 // }

          // doesn't work because of https://issues.scala-lang.org/browse/SI-6459
          // val enumValue = mirror.reflectField(enumRef.asTerm).get
          val enumClass = cm.runtimeClass(enumRef.owner.asClass)
          val enumValue = enumClass.getDeclaredField(enumRef.name.toString).get(null)

     Before the introduction of NullaryMethodType, a polymorphic nullary method (e.g, def isInstanceOf[T]: Boolean) used to be typed as PolyType(tps, restpe), and a monomorphic one as PolyType(Nil, restpe) This is now: PolyType(tps, NullaryMethodType(restpe)) and NullaryMethodType(restpe) by symmetry to MethodTypes: PolyType(tps, MethodType(params, restpe)) and MethodType(params, restpe)

     Thus, a PolyType(tps, TypeRef(...)) unambiguously indicates a type function (which results from eta-expanding a type constructor alias). Similarly, PolyType(tps, ClassInfoType(...)) is a type constructor.

     A polytype is of kind * iff its resultType is a (nullary) method type.

     Check well-kindedness of type application (assumes arities are already checked) -- @M

     This check is also performed when abstract type members become concrete (aka a "type alias") -- then tparams.length==1 (checked one type member at a time -- in that case, prefix is the name of the type alias)

     Type application is just like value application: it's "contravariant" in the sense that the type parameters of the supplied type arguments must conform to the type parameters of the required type parameters:

     - their bounds must be less strict
     - variances must match (here, variances are absolute, the variance of a type parameter does not influence the variance of its higher-order parameters)
     - @M TODO: are these conditions correct,sufficient&necessary?

     e.g. class Iterable[t, m[+x <: t]] --> the application Iterable[Int, List] is okay, since List's type parameter is also covariant and its bounds are weaker than <: Int

     Tests whether the argument (`arg0`) is a reference to the receiver object (`this`).

     Tests whether the argument (`arg0`) is a reference to the receiver object (`this`).

     The `eq` method implements an equivalence relation on non-null instances of `AnyRef`, and has three additional properties:

     - It is consistent: for any non-null instances `x` and `y` of type `AnyRef`, multiple invocations of `x.eq(y)` consistently returns `true` or consistently returns `false`.
     - For any non-null instance `x` of type `AnyRef`, `x.eq(null)` and `null.eq(x)` returns `false`.
     - `null.eq(null)` returns `true`.

     When overriding the `equals` or `hashCode` methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (`o1 eq o2`), they should be equal to each other (`o1 == o2`) and they should hash to the same value (`o1.hashCode == o2.hashCode`).

       `true` if the argument is a reference to the receiver object; `false` otherwise.

     A creator for existential types. This generates:

     where `tpe1` is the result of extrapolating `tpe` with respect to `tparams`. Extrapolating means that type variables in `tparams` occurring in covariant positions are replaced by upper bounds, (minus any SingletonClass markers), type variables in `tparams` occurring in contravariant positions are replaced by upper bounds, provided the resulting type is legal with regard to stability, and does not contain any type variable in `tparams`.

     The abstraction drops all type parameters that are not directly or indirectly referenced by type `tpe1`. If there are no remaining type parameters, simply returns result type `tpe`.

     Given a set `rawSyms` of term- and type-symbols, and a type `tp`, produce a set of fresh type parameters and a type so that it can be abstracted to an existential type. Every type symbol `T` in `rawSyms` is mapped to a clone. Every term symbol `x` of type `T` in `rawSyms` is given an associated type symbol of the following form:

     type x.type <: T with Singleton

     The name of the type parameter is `x.type`, to produce nice diagnostics. The Singleton parent ensures that the type parameter is still seen as a stable type. Type symbols in rawSyms are fully replaced by the new symbols. Term symbols are also replaced, except for term symbols of an Ident tree, where only the type of the Ident is changed.

     On the other hand, this also means that usage scenarios of the universe will differ from the conventional ones. For example, we have to do additional cleanup in order to prevent memory leaks: http://groups.google.com/group/scala-internals/browse_thread/thread/eabcf3d406dab8b2.

     Test whether the dynamic type of the receiver object is `T0`.

     Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression `1.isInstanceOf[String]` will return `false`, while the expression `List(1).isInstanceOf[List[String]]` will return `true`. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.

     returns

       `true` if the receiver object is an instance of erasure of type `T0`; `false` otherwise.

     The raw to existential map converts a raw type to an existential type.

     The raw to existential map converts a raw type to an existential type. It is necessary because we might have read a raw type of a parameterized Java class from a class file. At the time we read the type the corresponding class file might still not be read, so we do not know what the type parameters of the type are. Therefore the conversion of raw types to existential types might not have taken place in ClassFileparser.sigToType (where it is usually done).

     Unlike compiler universes, reflective universes can auto-initialize symbols on flag requests.

     scalac wasn't designed with such auto-initialization in mind, and quite often it makes assumptions that flag requests won't cause initialization. Therefore enabling auto-init leads to cyclic errors. We could probably fix those, but at the moment it's too risky.

     Reflective universes share codebase with scalac, but their surface is much smaller, which means less assumptions. These assumptions are taken care of in this overriden `shouldTriggerCompleter` method.
